Description

Technical Field

[0001] This utility model relates to the field of sliding window technology, specifically to a sliding window structure with a detachable screen. Background Technology

[0002] In the construction industry, sliding windows are widely used due to their advantages such as easy opening and not occupying indoor or outdoor space. As an important component of sliding windows, screens can effectively block mosquitoes, dust, and other pests from entering the room, improving the comfort of the indoor environment. Traditionally, the bottom of the screen on a sliding window is engaged with the outer edge of the bottom of the window frame to achieve the sliding of the screen. That is, when installing the screen, the bottom of the screen needs to be secured to the outer edge of the bottom of the window frame first, and then the top of the screen needs to be secured to the outer edge of the top of the window frame. The screen is positioned on the window frame through a two-way snap-fit. However, during installation, the screen needs to be tilted back and forth to make the bottom or top snap-fit ​​first, and then tilted left and right to make the top or bottom snap-fit ​​again. The whole installation process is relatively complicated and requires a lot of force to achieve the snap-fit ​​between the screen and the window frame. Conversely, it is more difficult to disassemble the screen, resulting in low overall disassembly and assembly efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sliding window structure with an easily detachable screen, thus solving the problem of the difficulty in detaching and installing screens on traditional sliding windows.

[0004] To achieve the above objectives, this utility model provides a sliding window structure with an easily detachable screen, including a window frame and two window sashes that cooperate with the window frame. The window frame includes a bottom frame and a slide rail disposed on the bottom frame for cooperating with the window sashes to allow the window sashes to slide along the length direction of the bottom frame. The bottom frame has a bend with a retaining edge on its outer side. The window frame also includes a screen and a frame that covers the screen. A sliding structure is provided between the frame and the retaining edge for the frame to slide along the length direction of the retaining edge. The outer wall of the frame is bent outward toward the retaining edge to form a first anti-detachment edge, and the inner wall of the frame is bent inward toward the retaining edge to form a second anti-detachment edge. The bottom wall of the frame and the top wall of the retaining edge are fitted with a gap. The frame is provided with a connection structure for detachably connecting the second anti-detachment edge to the frame so that when the second anti-detachment edge is separated from the frame, the frame can detach from the window frame along the width direction of the retaining edge.

[0005] The advantages of adopting the above technical solution are as follows: By setting a sliding structure between the frame and the edge, the screen frame can slide smoothly along the length of the edge. Combined with the dual anti-detachment design of the first and second anti-detachment edges, it can effectively limit the displacement of the frame in the width direction. The bottom wall structure with gap fit reduces frictional resistance. The detachable connection structure allows the second anti-detachment edge to be separated from the frame. Therefore, no high force needs to be applied to the screen during disassembly. It can be detached along the outside of the edge simply by releasing the connection structure. During installation, it can also be quickly positioned through the sliding and connection structures. This completely changes the complicated operation process of traditional screens that require repeated tilting and snapping, significantly improving the convenience and efficiency of screen installation and removal, while taking into account structural stability and anti-detachment performance.

[0006] The present invention further comprises: the connecting structure including a plurality of first connecting holes through the second anti-detachment edge and a plurality of second connecting holes on the frame, wherein the plurality of first connecting holes and the plurality of second connecting holes correspond one-to-one and are coaxially aligned, and a connecting shaft is threadedly connected to each of the first connecting holes, wherein the end of the connecting shaft is threadedly connected to the coaxially aligned second connecting hole.

[0007] The advantages of adopting the above technical solution are as follows: The above technology uses a threaded connection structure with a first connecting hole and a second connecting hole that connects to the second anti-detachment edge and the frame, providing a reliable detachable connection between the second anti-detachment edge and the frame. The stability of the threaded connection ensures that the screen will not loosen due to vibration or other factors during use. During disassembly and assembly, the connecting shaft can be installed and removed simply by rotating it, without the need for additional tools or complicated steps. This structure transforms the high operating force requirement of traditional snap-fit ​​connections into a refined threaded fit, which not only ensures the connection strength but also allows users to easily separate and fix the second anti-detachment edge. This makes the disassembly and assembly process of the screen more labor-saving and efficient during maintenance and cleaning, while avoiding damage to the window frame or screen caused by frequent operations.

[0008] The present invention further comprises: a limiting edge protruding horizontally along the length direction of the second anti-detachment edge on the inner wall of the second anti-detachment edge; a plurality of the first connecting holes are provided through the limiting edge; a limiting groove for the limiting edge to be inserted is provided on the inner side wall of the frame; and a plurality of the second connecting holes are connected to the inner wall of the limiting groove.

[0009] The advantages of adopting the above technical solution are as follows: The matching design of the limiting edge and the limiting groove in the above technology provides a precise positioning guide for the connection between the second anti-detachment edge and the frame. The limiting edge protrudes horizontally along the length direction of the second anti-detachment edge and is placed in the limiting groove of the frame. This not only ensures that the first connecting hole and the second connecting hole are coaxially aligned during installation, avoiding connection difficulties caused by misalignment, but also restricts the lateral displacement of the second anti-detachment edge when the connecting shaft is not installed, enhancing the stability of the screen during installation. This structural design makes the threaded connection of the connecting shaft smoother. At the same time, the limiting structure distributes some of the force during use, improving the reliability of the overall connection structure and avoiding loosening or deformation caused by long-term use. This further optimizes the installation and removal experience and structural strength of the screen.

[0010] This utility model further comprises: the bottom wall of the frame is connected to the inner wall of the first anti-detachment edge and the inner wall of the second anti-detachment edge with a smooth arc surface to form a first arc surface; the sliding structure includes a plurality of movable balls, which are arranged in pairs on the two first arc surfaces; the movable balls on the same side are arranged along the length of the frame; each movable ball is provided with a movable hole on the two first arc surfaces; each movable ball is rolled on the corresponding movable hole; the diameter of the opening of the movable hole is smaller than the diameter of the movable ball; the top wall of the retaining edge is connected to the outer wall and the inner wall of the retaining edge with a smooth arc surface to form a second arc surface; the movable balls are arranged in pairs and are movably engaged with the two second arc surfaces; the two first arc surfaces and the two second arc surfaces correspond one-to-one and are arranged opposite each other; the first arc surface and the corresponding second arc surface combine to form a raceway for the movable balls to roll.

[0011] The advantages of adopting the above technical solution are as follows: The rolling track structure formed by the movable ball and the first and second arc surfaces in the above technology transforms the sliding friction of the traditional sliding structure into rolling friction, which significantly reduces the frictional resistance between the frame and the edge, making the screen window slide more smoothly and effortlessly along the edge. The movable ball is limited by the movable hole with an opening smaller than its own diameter, which not only ensures the free rolling of the ball but also prevents it from falling off. Combined with the smooth transition design of the arc surface, a stable rolling fit relationship is formed. This structure not only makes the sliding operation of the screen window easier during installation without applying excessive force, but also reduces the wear and tear on the frame and edge during long-term sliding, extending the service life of the components. At the same time, it improves the flexibility of the screen window movement, making the push-pull operation in daily use more convenient and comfortable, taking into account both functionality and durability.

[0012] The present invention is further configured such that the length of the second anti-detachment edge is greater than the length of the first anti-detachment edge.

[0013] The advantages of adopting the above technical solution are as follows: The design of the second anti-detachment edge being longer than the first anti-detachment edge creates a structural advantage of strong anti-detachment on the inside and easy disassembly and assembly on the outside. The longer second anti-detachment edge bends towards the inside of the guard edge, which can effectively prevent the frame from detaching outward, enhancing the anti-detachment performance of the screen window during use and preventing the screen window from falling off due to accidental collisions or vibrations, thus improving safety. The shorter first anti-detachment edge is on the outside, which not only meets the requirement of limiting the outer side of the frame but also reduces interference during disassembly and assembly, making it easier to separate the second anti-detachment edge from the frame. This asymmetrical anti-detachment edge design, while ensuring structural stability, cleverly balances the anti-detachment function and ease of disassembly and assembly, avoiding the problems of difficult disassembly and assembly or insufficient anti-detachment that may be caused by traditional symmetrical structures, thus optimizing the overall structural design of the screen window.

[0014] The present invention is further provided that: the bottom wall of the first anti-detachment edge is bent toward the outer wall of the guard edge to form a wear-resistant edge, and the wear-resistant edge is made of wear-resistant rubber material.

[0015] The advantages of adopting the above technical solution are: the wear-resistant edge of the bottom wall of the first anti-detachment edge is made of wear-resistant rubber material, which can effectively reduce the direct friction between the frame and the edge during the sliding process, reduce wear and tear caused by long-term use, and extend the service life of the screen and window frame. The bending design of the wear-resistant edge makes it form a flexible contact with the outer wall of the edge, which not only plays a buffering role and reduces noise during sliding, but also adapts to a certain degree of installation error and improves the fitting accuracy.
